The first relevant graph I used was regarding the total property transactions in 2016 upto November:

We now have the December numbers added, which show a dip, albeit shallow.

The year 2016 has closed with more than 400,000 registered sales (403,743), something that did not happen since mid-2011. Again, the above data is for the whole of Spain, so let's check what can we deduce for the Costa del Sol. Registradores.org has already published the full 2016 year results, so we now know that the 5 provinces with the largest property purchases are:

Madrid

58,752

Barcelona

46,415

Alicante

29,688

Málaga

26,436

Valencia

21,963

So we may conclude that Malaga/Costa del Sol is one of the most popular regions at the trimester and yearly level.

Unfortunately price data is not out yet, but an interesting datapoint is the percentage of foreign buyers: 13.5% of property purchases in 2016 were by foreigners. British buyers were lower compared to 2015, as expected, from 23.9% to 16.4%, however still ahead of German and French buyers at 9% and 8% respectively.

So in short, I personally do not see any strong signals of Brexit-related worry judging from the only actions that matter, those of the wallet. Nevertheless, one has to acknowledge the dip in the British-originated purchases in the last month of 2016. Still pending are the price data, which I will inform you on as soon as they are out.
